cs_all_violated(+CS, -Cstr)

Get all violated constraints in the constraint set
CS
Constraint set
Cstr
A list of constraints (output)

Description

Returns a list of all currently violated constraints in the constraint set, i.e. all the constraints whose violation count is currently nonzero.

If the constraints were added with aliases (see :~ /2), the alias term is retrieved instead of the constraint goal.

Modes and Determinism

Examples

    ?- [X, Y] tent_set [3, 4], CS :~ (X $= Y), CS :~ (X $\= Y), cs_all_violated(CS, C).
    X = X{3 -> 0}
    Y = Y{4 -> 0}
    CS = constraint_set(TotalVio{1 -> 0}, ...)
    C = [X{3 -> 0} $= Y{4 -> 0}]
    There are 2 delayed goals.
